The FM25TX is an FM transmitter with a power output of 2.5W. It is compatible with audio decoders and integrates audio decoding and FM signal transmission functions, while also functioning as an FM radio. It features six functions in one: Bluetooth audio, USB decoding playback, AUX input, PC sound card, FM transmitter, and FM radio. The chip used is a SOC, integrating a 32-bit MCU and a dedicated aDSP for audio decoding. It employs hardware decoding, ensuring system stability and sound quality. The audio signal can be set with EQ sound effects modes, improving the quality of FM transmission. Users can set their preferred modes according to the music playback quality.
FM Transmitter:
Function: It can transmit Bluetooth audio, USB, AUX, and PC audio signals via FM, which can then be listened to on a radio.
FM Transmit Power: 2.5W
Decoding Playback Function: It can connect Bluetooth audio, USB, AUX, and PC audio signals to an amplifier through a 3.5mm audio output port.
EQ Sound Effect Modes: Normal, Rock, Country, Classical.
USB Flash Drive Decoding Formats:
1. Supports MP3, WAV, WMA, and FLAC formats; supports breakpoint and track memory functions; maximum capacity 128GB.
2. Supports all bitrates 11172-3 and ISO13813-3 layer 3 audio decoding.
3. Supported sampling rates (kHz): 8/11.025/12/16/22.05/24/32/44.1/48.
4. Supports EQ sound effects settings.
5. Supports single-track loop playback; sequential loop playback of all files on the USB flash drive, starting from the first track by default.
Bluetooth Reception:
1. Bluetooth version 5.3, supports HFP/A2DP/AVRCP/HSP/GAVDP/IOP/SPP/BLE, with a range of approximately 10 meters.
2. Class 2 4dBM frequency range: 2.4GHz-2.480GHz.
3. Supports EQ sound effect settings.
PC Sound Card:
Driver-free USB sound card function. Connects the computer and player via USB, allowing you to input computer audio to an amplifier or output it via an FM transmitter for radio reception.
AUX Audio Input:
Inputs audio signals from other players via the AUX input interface and transmits them as FM signals. Outputs can also be connected to an amplifier via the AUX output port.
Radio:
1. Displays the number of received stations, current station number, current station frequency, and saves the received station information.
2. Receiving frequency: 87.5MHz-108MHz, does not support Japanese frequencies.
3. Automatic station reception/manual tuning.
FM Transmitter:
1. Stereo transmission: Transmits stereo if the input is stereo, and transmits mono or a mix if the input is mono or a mix. This setting cannot be configured.
2. Stereo separation >35dB.
3. Transmitting frequency: 76MHz-108MHz, supports global frequencies.
4. Set the frequency step to 0.1MHz.
5. Transmit power: 2.5W.
6. Transmission distance depends on the environment and the receiver sensitivity of the radio, but the biggest factor is the transmission power; generally, it should be above 1000 meters.
